Episode 69: In this episode of Critical Thinking - Bug Bounty Podcast we’re joined by Johan Carlsson to hear about some updates on his bug hunting journey. We deep-dive a CSP bypass he found in GitHub, a critical he found in GitLab's pipeline, and also talk through his approach to using script gadgets and adapting to highly CSP'd environments. Then we talk about his transition to full-time bug hunting, including the goals he’s set, the successes and challenges, and his current focus on specific bug types like ReDoS and OAuth, and the serendipitous nature of bug hunting.

We're new to this podcasting thing, so feel free to send us any feedback here: info@criticalthinkingpodcast.io
